Drug delivery systems are described that include sensors and processing circuitry that can detect operating events, such as flow rates and drug delivery, in various types of inhalers, such as dry powder inhalers, metered dose inhalers, nasal inhalers and nebulisers. The system has three main parts –a drug delivery device that makes measurements during operation, a user device that receives measurement data transmitted from the drug delivery device; and a remote server that processes the measurement data and determines various operating parameters of the drug delivery device, including compliance data indicating correct of incorrect use of the drug delivery device. At least the compliance data is transmitted back from the remote server to the user device for output to the user to indicate correct or incorrect use of the drug delivery device. |
